HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

2-Isopropyl-N,2,3-trimethylbutanamide features a sterically hindered amide core that enhances stability under reactive conditions. This bulky, moisture-tolerant structure facilitates clean coupling reactions in synthetic workflows. The branched alkyl framework imparts solubility in organic media and reduces undesired side reactivity, enabling efficient incorporation into complex molecular architectures.

Application

2-Isopropyl-N,2,3-trimethylbutanamide serves as a sterically hindered amide building block, enabling selective amidation reactions in complex molecule synthesis. Its branched alkyl architecture enhances stability and reduces undesired side reactivity, facilitating purification and compatibility with diverse functional groups. This compound functions effectively in peptide coupling and heterocycle formation workflows where steric control is critical.
